Summary, etc. | L’avancée du front pionnier dans le Sud de l’État brésilien du Pará a entraîné un défrichement intensif de la forêt dense humide au profit de pâturages. Dans les petites et moyennes exploitations, ces pâturages montrent maintenant des signes de dégradation qui peuvent entraîner l’abandon de terres et la migration de familles vers d’autres lieux. Depuis 20 ans, les agriculteurs de Santa Maria ont réagi en plantant de nouvelles graminées fourragères supposées résoudre ces problèmes. L’introduction de la dernière espèce, Andropogon gayanus, est l’innovation d’un agriculteur adoptée peu à peu par tous. Elle produit une forte biomasse, résiste aux insectes et, dans un système où la pression du troupeau est faible, réussit à concurrencer les adventices. Les agriculteurs ayant donné priorité aux pâturages ont été les premiers à la tester. Le succès de l’innovation dépend de sa capacité à répondre à des problèmes donnés mais se rapporte également aux perceptions que chacun s’en fait. |

Summary, etc. | Innovative farmers: a new grass on the pastures of Santa Maria (Brazilian Amazonia)In the region of Marabá, Amazonia, the advance of the pioneer front has lead to an intensive clearing of the rainforest and to the increase of pastures that now show signs of degradation: the invasion of weeds and insect infestations. Most of the farmers perceive these problems as inevitable. However, in the last twenty years, the farmers have tried to successively introduce four fodder grasses that supposedly will solve the problem. The species most recently introduced, Andropogon gayanus, was an innovation brought by one farmer, and then progressively adopted by all of the others in Santa Maria. This type of cyclic management, where cultivated plants give satisfaction in the first time and then should be replaced by others, has quickly brought on dynamic innovations. The farmers who have prioritized pastures are constantly seeking solutions to slow down the degradation which, in the long term, implies abandoning the land and migrating with their families. Not surprisingly, they were the first to test and approve the new grass species. Those who adopted the innovation with reticence are more interested by local development alternatives that aim to ensure the sustainability of the farmers’ activities (diversification, perennial cultures). The success of each innovation depends on its capacity to respond to the present problems, but also is contingent on the local perceptions of the degradation and sustainability process. |
